By means of non-limiting example, the top 11 of buffer container 10 preferably constitutes exterior contour with the wrinkle shape handle 16 with sidewall 17 and 17 '.The benefit of this set will be discussed in the back.
In one embodiment of the invention, buffer container 10 and sample divider 20 are in place by 19 clampings of clinching steady arm at first.When buffer container 10 by be pressed into downwards pierce through parts 23 pierce through on the edge 24 time, the second clinching steady arm 19 ' is with regard to clamping and sealing buffer container 10, make it firmly to contact, pierce through the film 18 that can puncture whereby and make the damping fluid that is held in the buffer container 10 discharge (referring to Fig. 4 A) with sample divider 20.
In another embodiment of the present invention, the main part 13 of buffer container 10 has the thread outer surface 14 that is provided with for the coupling screw thread that forms on the inside surface 21 that is engaged on sample divider 20.Utilize this mode, buffer container 10 can be connected to (referring to Fig. 4 B) on the sample divider 20 in the close mode of liquid.Also can adopt other scheme that obtains the close connection of liquid, for example, on main part 13, form the elastic bumps (not shown), or the circulating application of one or more O shape is added on the main part 13.Or, can adopt also that liquid between the plane is close to be pressed into cooperation.
Preferably, the internal diameter size of the external diameter of sample divider 20 and buffering container 10 makes sample divider 20 and buffering container 10 when being connected, and frictionally meshes each other.
These parts are used to connect other shape of buffer container 10 and sample divider 20 and the parts of setting also are suitable for, as long as can make between buffer container 10 and the sample divider 20 with fluid communication.
The stung rupture of membranes 18 of buffer container 10 forms the barrier of fragile fluid impermeable, so that damping fluid is retained in the buffer container 10.Can sting rupture of membranes 18 can be formed by any non-active material, and these materials can be included in damping fluid in the buffer container 10, and can be punctured by the edge 24 that pierces through that pierces through parts 23 that forms in sample divider 20.Be suitable for forming the examples of materials that to sting rupture of membranes 18 and include, but is not limited to metal forming, polymeric membrane, glass and plastics.And, can sting rupture of membranes 18 can with appropriate size and shape, with pierce through the cut (score) that will break when edge 24 contacts or pre-stressed area (not shown) and form.
Referring now to Fig. 6 and 7, sample divider 20 comprises inside surface 21, outside surface 22 and inner bottom part 27.Sample divider 20 also comprises and pierces through parts 23.What the upper limb that pierces through parts 23 comprised the point point pierces through edge 24, and when buffer container 10 was connected on the sample divider, this pierced through the stung rupture of membranes 18 that the edge just contacted and pierced through buffer container 10, and the damping fluid (not shown) is discharged.The shape that pierces through parts 23 is fit to flowing of damping fluid.
Continuation is with reference to Fig. 6 and 7, and sample divider 20 also comprises the hollow channel parts 26 of lengthening.Inner chamber 28 extends to the bottom 27 of sample divider from the tip of passage component 26, its reason will be explained in the back.
Translate into Fig. 8-11 now, below will describe filtrator 30 and strip 40.
Except FLOW CONTROL and from specimen the impurity screening, filtrator 30 also clamping strip 40 is located in the chamber 56 of test strip container 50 (as shown in figure 11).Specify when contact when strip 40 and filtrator 30, just can obtain the fluid transmission of good homogeneous.
A kind of mode that realizes this point is, makes filtrator 30 have two parts, and these two part amalgamations are together the time, and just having stopper and its setting can be clamped in strip 40 between them.So filtrator 30 comprises the fixture of strip 40.
As shown in Figure 8, filtrator 30 comprises flat 31 and has the barbed portion 32 of breach 36, by hinges 33 these two parts linked together.Hinges 33 makes the amalgamation be in the same place (shown in Figure 10 and 11) with barbed portion of the smooth of filtrator 30.
If necessary, hinges 33 can enough any other suitable being used to connects smooth and structure barbed portion 31,32 replaces.Or, need not smooth and barbed portion is coupled together, but these two parts are in the part 57 of inserting test strip container 50 (its shape is fit to hold filtrator 30) time, still want amalgamation together.
Referring now to Fig. 8 and 9, the shape of breach 36 is preferably shaped to the end 44 that can firmly receive strip 40.The thickness of the end 44 of the depth ratio strip 50 by making breach 36 is smaller, and end 44 is captured in securely between the flat and barbed portion 31,32 of the filtrator 30 after the assembling.Breach 36 also is easy to end 44 secure capture with strip 40 between the flat and barbed portion 31,32 of filtrator 30, and can not make the improper distortion of filtrator.
In case smooth and barbed portion 31,32 amalgamation of filtrator 30 together, just the end 44 with strip 40 is captured in therebetween (as shown in figure 11), so they must be fixed together.For the smooth and barbed portion 31,32 with filtrator 30 is clamped together, flat 31 is furnished with protruding pin 35, and barbed portion 32 is furnished with coupling recess 34.When the shape of pin 35 and recess 34 is fit to (pin 35 is wideer slightly than recess 34), they will be by means of interface fit, and will smoothly be clamped together with barbed portion 31,32, thus with strip 40 fix in position.Or, utilize a reverse taper (not shown), in this case, pin 35 is stitched to a time-out in smooth and barbed portion 31,32 and is bent downwardly slightly, and when aliging with recess 34, pin 35 bend into downwards in the recess 34 then.Still by means of indefiniteness replacement type example, make the welding of pin and recess or be bonded together, link together or utilize any other suitable technology to be fixed together with securing member, these do not depart from the scope of the present invention.
Still by means of non-limiting example, filtrator 30 can be that inside has the columniform single parts (not shown) of being roughly of slit, and the position of this slit is general corresponding with breach 36.By making slit more smaller than breach 36, and the end 44 that makes strip 40 is by means of simply in place by the press fit clamping.That is to say, utilize one or more thinner hard blades, the end 44 of strip 40 is forced in the slit in place, thereby end 44 is located in slit.
Another aspect of the present invention comprises, a plurality of strips are set in filtrator.By means of indefiniteness embodiment, Figure 26 A expresses the part of Sample testing device 1, in this device, and two strip 40a of filtrator 30 clampings, 40b.Should be appreciated that, these two strip 40a, each of 40b can both be implemented different checks.Or, in order to improve accuracy, these two strip 40a, 40b can implement same check.
Figure 26 B is presented as another kind of strip and arranges and the filtrator 30 of structure; And these strips are to be positioned on the line in Figure 26 A, and in Figure 26 B, filtrator 30 has and is used to receive the strip (not shown) so that the opening 6 that strip is set parallel to each other.Figure 26 C expresses another example structure, wherein arranges three opening 6 (not shown) around the center C of filtrator 30 for these strips.
Also can adopt a large amount of strips, and can in every way these strips be arranged in the filtrator 30, such as be arranged along a straight line (shown in Figure 26 A), along arrangement of curves, be arranged on the limit of geometric configuration (for example triangle) or around the center arrangement (shown in Figure 26 C) of filtrator 30.Preferably, the layout of strip makes them be easy to be observed.
In any suitable mode, for example utilize above-mentioned layout and technology, these a plurality of strips are clamped in the filter assemblies.It should be appreciated by those skilled in the art that used strip number can determine strip is fixed to mode in the filtrator.
Be also to be understood that can having more, the blood of volume needs to collect when adopting a more than strip 40.The shape of the passage component 26 by revising sample divider 20 can realize this point so that extract the more blood of volume out in the sample collection process.
In addition,, then need to increase the amount of the damping fluid that is held in the buffer container 10, be properly handled to guarantee strip 40 if adopt a more than strip 40.By increasing buffer container 10,, just, can realize this point by increasing the amount of the damping fluid that is held in the buffer chamber 10 if used buffer container 10 is not full of fully with damping fluid among perhaps single strip embodiment.
Be contemplated that also the damping fluid that is provided is fit to use with all strips when utilizing a plurality of strips to implement more than one check.
In another embodiment of the present invention, can prepare the single strip that comprises a plurality of checks on it.Such when comprising the strip of a plurality of checks when adopting, each check that used damping fluid should be suitable for implementing on this strip.
Any suitable strip form known or later exploitation all is available at present.By means of non-limiting example, this strip can be the conventional chemical bar that has the change color that takes place according to assay on immunochromatography (ICT) bar or the strip.And the ICT bar can be the quantitative aurosol-based on the sxemiquantitative paramagnetic particle of instrument-based on sxemiquantitative or quantitative latex particle or other kind of instrument of aurosol-red color visible.Moreover cited herein strip types is explanation for example just, and not qualification effect.
Now with reference to Fig. 1 and 12 test strip container 50 is described.
Continuation is with reference to Fig. 1 and 12, and test strip container 50 preferably is generally columniform container, and this container is in its bottom 51 closures, and opens at its openend 52, thus all parts that can load sample proving installation 1.Because test strip container 50 is held buffer container 10, sample divider 20, filtrator 30 and strip 40, so the profile of test strip container 50 is stage by stage from the side of Figure 12.By this way, each phase zone is all roughly the same with the size of its that part of Sample testing device 1 that is comprised.The narrowest the longest part of test strip container 50 is the chambers 56 corresponding to strip 40.Part 57 correspondences of test strip container 50 are also held filtrator 30, and wideer slightly than chamber 56.The part 58 of test strip container 50 is wideer slightly than part 57 again conversely, and corresponding and hold buffer container 10.
As shown in figure 12, test strip container 50 is 51 closures in the bottom, and 52 open in the end.The size of test strip container 50 in position 57 makes it can hold filtrator 30 and the strip 40 that is fixed in the filtrator 30.Filtrator 30 is engaged in the test strip container 50, and does not directly contact with the expose portion of strip 40.58 size makes it can be by frictional fit clamped sample gatherer 20 and buffering container 10 securely to test strip container 50 in the position.By means of non-limiting example, buffer container 10 and sample divider 20 can weld or bond in place.And, before with sample divider 20 and buffering container 10 insertion test strip container 50, buffer container 10 can be connected on the sample divider 20.
As shown in Figure 1, strip 40 itself can be all a kind of strips as is known.Usually utilize the reagent compatible to handle these strips with the check of being implemented.
If strip 40 is visual strip (preferably), be to determine that by the visual display of observing on the strip structure of test strip container 50 should make strip 40 be observed so with regard to meaning assay.By forming whole test strip container 50, can accomplish this point with transparent material (for example glass or plastics).Or, can adopt opaque or non-transparent material, and at least one transparency window 55 is formed in the chamber 56 of test strip container 55, thereby can observes strip 40 by this window.
Also should expect, can utilize instrument (separately use or use) to come reading test strips with visualization.
Though thinking at present preferably provides the buffer container 10 of the Sample testing device 1 that damping fluid is housed, buffer container 10 also can be empty, and fills damping fluid by the user.In this set, buffer container 10 can be fully and exactly part by making from close material.In order to fill buffer container 10, the user need take a syringe that contains the q.s damping fluid, and the pushing syringe syringe needle passes from close material.In case syringe needle is positioned at the inside of buffer container 10, the user just damping fluid is injected buffer container and with syringe needle from wherein withdrawing from.Then, seal the opening that causes by syringe needle from close material, thereby damping fluid is retained in the buffer container.
Now with reference to Figure 13-15 a replacement type embodiment of the present invention is described.

The use of Sample testing device
Realize function of the present invention in the following manner: specimen is mixed with damping fluid, filter the potpourri that is generated, utilize a slice reactive test material to absorb this potpourri then.Reactive test material is the material that can change one or more characteristics when predetermined substance exists.Herein, the characteristic that changes is preferably visual.By means of non-limiting example, when being applied to some material on the strip, strip can variable color or is launched one or more line, band, point or figure.The mode that realizes this point will be discussed below.
In case removed the packing of Sample testing device 1, just be prepared as follows this device, so that use.
Detected materials sample (not shown) is inserted sample divider 20.The examples of fluids that can be used as the sample in the test macro of the present invention includes, but is not limited to: saliva, celiolymph, serum, whole blood, blood plasma, vaginal secretion, sperm and urine.These body fluid can obtain on one's body from humans and animals.In addition, the fluid that obtains from plant, trees, soil, environment and other source also can be used as sample.Character per sample, any in can several modes are packed sample in the sample divider 20.
If liquid is not excessive thickness, just can pass through capillary action, with the inner chamber 28 of its suction passage component 26 that makes progress.By means of example, the tip of passage component 26 is dipped in the patients'blood, thereby blood is made progress in the suction inner chamber 28.In some cases, patient can bleed arbitrarily, such as, if patient has cut wound and open wound.Or, need or preferably, draw blood on one's body from patient.By finger, toes or ear-lobe, can realize this point with prong thorn patient.Bleed greatly after the liquid collecting one, the tip of passage component 26 is dipped in the drop of blood, and capillary action will be the make progress inner chamber 28 of suction passage component of blood.
Because suspecting capillary action is to be determined by the viscosity of liquid, and can select to form size and composition, the shape of inner chamber 28 and the composition of passage component 26 of material capillaceous, so that testing liquid is passed through capillary action suction inner chamber 28.Therefore the viscosity of testing liquid will determine the structure of passage component 26.
If detected materials is liquid and is contained in the container such as beaker or test tube, the tip of passage component 26 can be dipped in the liquid.Then, by capillary action with liquid suction inner chamber 28.
As mentioned above, utilizing after capillary action by passage component 26 upwards is pumped into the inner chamber 28 of sample divider 20 with liquid, just buffer container 10 interior damping fluid or the thinning agents that comprised are discharged.Then, making after sample divider 20 has been located in the test strip container 50, under the effect of gravity, and the extruding buffer container when breaking under the influence of possibility applied pressure, damping fluid is downward through sample divider 20.When damping fluid continued to flow downward, it passed the inner chamber 28 of sample divider, and it mixes with blood sample in the inner chamber herein.Subsequently, blood and the contacted filter 30 of buffering liquid mixture, and filtrator 30 roles are to avoid haemocyte and any impurity from wherein passing through.By this way, only there is liquid can continue to be downward through on the strip 40 that filtrator 30 arrives in the test strip container 50.
Or, in the substrate 27 that liquid is dripped to sample divider 20,, fluid sample is located in the inner chamber 28 and being dripped.Moreover capillary action will be liquid suction inner chamber 28.Testing liquid is contained under the situation in syringe and the volumetric pipette, and this method is preferred.
If detected materials is very sticking or or even solid-state, then just material is dripped in the substrate 27 of sample divider 20.
In case sample is detained by sample divider 20, sample is exposed in the damping fluid of being detained in the buffer container 10, and no matter whether needs stirring (for example jolting).This requires buffer container 10 interior damping fluids of being detained to flow out and contacts with sample.
Referring now to Fig. 1, be positioned in the sample divider 20 by making buffer container 10, so that the edge 24 that pierces through that makes the film 18 of buffer container 10 be pierced parts 23 punctures, can realize this point.If buffer container 10 and sample divider 20 have matching thread 19 and 29 respectively,,, this point is worked so that screw thread 19 and 29 is located for fit engagement by making buffer container 10 and sample divider 20 in place together.Compressible grip and the distortion of screw thread 19 and 29 by grasping buffer container 10 then, and meshing, and owing to the relative rotation between the two, and buffer container 10 is pushed to the substrate 27 of sample divider 20.When buffer container 10 was shifted to sample divider, the edge 24 that pierces through that film 18 just is pierced parts 23 punctured.Then, under the effect of gravity, the liquid in the buffer container 10 can outwards and flow downward, and contacts with sampling receptacle 20 interior samples of being detained.
If necessary, the film 18 of buffer container 10 can have the vulnerable area (not shown), and film does not at first break when being extruded herein.The residing position of this vulnerable area is arrived its edge contact that pierces through that can be pierced parts 23.Form such vulnerable area by cut, punching press, etching etc.Now, when being coupled to sample divider 20 in the sample divider and after buffer container shifts to sample divider 20 with buffer container again, piercing through edge 24 and just impact and tear described vulnerable area.Then, damping fluid just flows out and and sample mix.In another embodiment of the present invention,, can make the buffer container rotation, further tear this vulnerable area whereby and provide bigger opening for the outflow of damping fluid piercing through after edge 24 impacts and tear vulnerable area.
If necessary, by the sidewall 17,17 ' of extruding compression handles 16, can promote liquid from buffering container 10, to flow out.This will make the volume distortion of buffer container 10 and reduce, thereby make damping fluid from wherein discharging.
If buffer container 10 has the sealing ring 19 that replaces screw thread, so just utilize pressure on the compression handles 16 with buffer container to lower compression.Moreover film 18 will be punctured, and damping fluid is discharged and contact with sample.
As a kind of replacement type structure, can form the sample divider 20 that does not pierce through parts 23.And the film 18 of buffer container 10 can have the vulnerable area (not shown), and film does not break earlier when being extruded herein.Form such vulnerable area by modes such as cut, punching press, etchings.Now, after being coupled to sample divider 20 in the sample divider, the compressible grip 16 of just pushing buffer container 10.This makes the pressure in the buffer container 10 raise, and breaks at vulnerable area up to film 18.Then, as mentioned above, damping fluid just flows out and and sample mix.
Subsequently, filter the potpourri of damping fluid and sample with filtrator 30.This can be avoided damping fluid or sample directly to contact with strip 40.By means of non-limiting example, if test sample is a blood, filtrator 30 is isolated leucocyte and red blood cell before just can contacting strip 40 at the potpourri of damping fluid and sample from sample.
By vertical clamping Sample testing device 1, gravity pushes away potpourri downwards.And, in the hole of capillary action with damping fluid and sample suction filtrator 30.Should be appreciated that liquid is subjected to the composition of filtrator 30 and the influence in aperture by the speed of filtrator.The reducing of aperture will make liquid flowing rate slow down, and the aperture increases liquid stream will be quickened.It can be essential that liquid stream by filtrator 30 is slowed down, because need damping fluid and sample to keep contacting of long period herein.
The flowing of damping fluid that filtrator 30 passes therethrough except adjustment and sample, also hold back the damping fluid that mixed and the solid particle in the sample.By this way, only there is liquid to arrive strip 40.Should be appreciated which kind of solid particle big young pathbreaker's decision of the hole (not shown) of filtrator 30 avoids arrive strip 40.
The filtering mixt of damping fluid and sample under the influence of capillary action and possible gravity, by suction downwards by filtrator 30, up to some mixed liquors finally with till the narrow end 44 of the strip 40 of filtrator 30 clampings contacts.Moreover capillary action and possible gravity are with the damping fluid and the sample suction strip 40 that are mixed.
Referring now to Fig. 1, the whole of damping fluid and sample flowed all on the direction of arrow A.
In case damping fluid that is mixed and sample react with strip 40 (the enough known modes of reaction energy take place), the outward appearance of strip 40 just can change, thereby the demonstration directly perceived of the assay of being implemented is provided.By the window 55 in the test strip container 50, or test strip container 50 own (if test strip container 50 is transparent), can observe this result.
In another embodiment of the present invention, the absorption pad 2 (as shown in Figure 1) that provides by using is caught some with the liquid that aforesaid sampling device 1 is checked, and can implement the check conclusive evidence.Pad 2 both can be equipped with Sample testing device 1, also can buy separately.By means of non-limiting example, independent pad 2 is to be used for exerting pressure and promoting the sort of pad of its blood coagulation to the finger tips that patient is stung.
Absorb liquid in case fill up 2, just will fill up 2 and be transported to remote laboratory, so that test separately.Utilize with finishing with strip and implement such check with the different rules of the method for checking interested situation or characteristic.By this way, utilize the fluid sample that takes out simultaneously that inspection is proved conclusively in the check of sampling device 1 enforcement.
Optional is to be decorated with circle 4, the zone that express liquid will be absorbed on the pad 2.This helps individual management check, so that fluid sample is put into the correct position of filling up on 2, and it also makes this conclusive evidence sample of remote lab analysis (knowing experimental material is positioned at which position on the pad 2).
Still randomly, can utilize on the pad this to enclose the aequum of stipulating sample to be collected.That is to say that the size of circle shows that collected sample size is to be used to prove conclusively the required minimum of suitable sample of check at least.
